On-Site Kitchen Spraying: What’s Safe, What’s Not — and How We Do It Differently

At Faded Mist, the majority of the spraying involved in a kitchen respray takes place away from your home, in our dedicated Finishing Studio.

This is a deliberate decision — not only for the quality of the finish, but for control, consistency, and safety.

That said, some elements of a kitchen simply can’t be removed. In those cases, limited on-site spraying is sometimes required. Understanding what’s sprayed on site, how it’s done, and what products are used is an important part of choosing the right approach.

Why on-site spraying needs careful consideration

Spraying paint indoors isn’t the same as decorating with a brush or roller.

Professional spray finishes atomise coatings into very fine particles. Those particles behave differently depending on the environment — airflow, access, lighting, and ventilation all play a role. A domestic kitchen isn’t designed to function as a spray booth, which introduces natural limitations.

There’s also an important distinction between limited on-site spraying and a full kitchen respray carried out entirely in the home.

Some companies carry out the entire respray on site. In certain cases, doors are removed and sprayed elsewhere. In others, doors are sprayed while still hung on their hinges. Homeowners are rarely told which approach is being used — or what the implications are.

Common issues with full on-site spraying can include:

• Hinges, fixings, and hardware being sprayed over

• Edges, returns, and internal faces being difficult to access properly

• Overspray settling into areas that are hard to mask perfectly

• Inconsistent results caused by lighting, airflow, and restricted working space

Even with good intentions, these constraints can affect both the finish and the overall experience within the home.

A note on two-part paints and isocyanates

Some kitchen respray companies use two-part (2K) coatings when spraying on site. These products often contain chemicals known as isocyanates.

Isocyanates are commonly used in industrial and automotive environments because they cure quickly and create hard finishes. However, when sprayed, they release hazardous gases that require industrial-grade ventilation and specialist respiratory protection to be handled safely.

Crucially, the risk doesn’t end once spraying stops.Two-part coatings can continue to gas off for several weeks after application, releasing harmful compounds long after the paint appears dry.

Exposure has been linked to respiratory issues, such as asthma and bronchitis, as well as skin irritation and allergic reactions, which is why these products are restricted to controlled industrial environments.

For this reason, isocyanate-based products are not suitable for use inside occupied homes. This is reflected in UK health and safety guidance, including information published by the Health and Safety Executive (HSE), which outlines the risks associated with spraying these materials in enclosed or poorly ventilated environments.

For a clearer understanding of the risks involved, we recommend carefully reading the following guidance from the Health and Safety Executive (HSE):

This isn’t about fear — it’s about understanding that certain products are designed for controlled, industrial settings, not domestic spaces

How we approach this differently

At Faded Mist, our process is designed to minimise risk and maximise consistency.

• All removable parts, such as doors and drawer fronts, are taken to our Finishing Studio and sprayed under controlled conditions.

• We never spray isocyanate-based coatings inside your home.

• Where limited on-site spraying is unavoidable (for fixed carcasses or panels), we use carefully selected, non-isocyanate alternatives suitable for residential environments.

• On-site areas are fully masked, with professional extraction and filtered air circulation used to manage overspray and maintain a controlled working environment.

  
  

This hybrid approach allows fixed elements to blend seamlessly with doors and panels sprayed off-site, while keeping on-site work precise, contained, and proportionate to what’s actually required.

Why we invest in a Finishing Studio

Our Finishing Studio allows us to control:

• Temperature

• Humidity

• Airflow

• Drying and curing times

This level of control reduces variables, improves consistency, and removes the need to rush. It also allows better access to edges, details, and return faces — areas that are often compromised during full on-site spraying.

It’s a practical investment in quality — and one of the reasons our finishes are designed to last.

What to ask any kitchen spraying company

If you’re comparing approaches, it’s reasonable to ask:

• What products will be sprayed inside my home?

• Are any two-part or isocyanate-based coatings used on site?

• Are doors and drawers removed and sprayed elsewhere — or sprayed in place?

• What happens to hinges, fixings, and hardware during spraying?

• How are edges, returns, and internal faces finished?

• How is ventilation managed during application?

Any reputable company should be happy to explain their process clearly.

The takeaway

On-site spraying isn’t automatically “bad” — but how much is done on site, and how it’s done, matters.

A full on-site respray means adapting parts of your home into a spray environment, with all the limitations that brings. Removing doors and components and spraying them in a controlled facility allows for greater consistency, better access to detail, and significantly less disruption within the home.

Our process is built around control, safety, and long-term results — not speed or shortcuts.
